Hi all, I have two 580s in SLI running on an i7 920 with a mild 3.2 overclock. The case is a Corsair Obsidian with the three stock fans and an additional four. Typical temps under load are 29C for the SSD, 30C for the HDD and 50C for the CPU. But the GTX 580s run 89C and 88C respectively after extended sessions (two to three hours) of demanding games like Crysis Warhead. Is this normal for an air-cooled case? Should I be worried? The GPUs are running at stock speeds.
Your temps are normal I get 85 c top card 83c bottem under furmark as reference using 800d case. I've not put them both together though there in slot 1 and 3 instead of 1 and 2
Thanks Rollo - that's good to know. I don't have room on my mobo to split the cards, so that's probably why they are running a bit hotter being so close together.
Not exactly the same situation but I have recently installed a 560 and my cases cooling is pretty poor but it has still never gone above 60c. even playing crysis warhead on max settings.
It's because the 800D is more aimed at watercooling than air cooling. if you had a HAF 932 or HAF x then your temps would be different. Just watercool them...
I'd love too - but I'm too scared I'd mess things up! I know, what a wuss, eh? I know virtually nothing about watercooling - is it possible just to wc the 580s - or would it be better to go the whole hog and do the entire system? And what happens when you switch components? I'm guessing a new mobo and CPU will be in the case by the end of the year.
Those temps are about right for your set up it all about air flow I found I removed all the PCI blanking plates and the air flow improved.
I can never get to sleep at night wondering how the hell you have a speed like that... What's your secret? On topic, it's quite a normal temperature for having two very powerful cards so close together. You could maybe upgrade the stock fans to something that pushes a little more air?
Living somewhere with ASk4 internet and the managed switches seem to have screwed up. So when the building is empty, thats what I get... Although they've upgraded it now, so i may max GB Ethernet this summer...
Yeah, those temps are nothing to worry about. The cards will throttle at 97C, which in these terms is quite a way off.
OK, thanks for all your advice guys. It looks like I don't need to worry too much then. I'll try removing the extra slot covers and see if that reduces temps even further. But having read Pete's guide I am very tempted to one day go for watercooling. I guess there are three basic ingredients: components, knowledge - and balls of steel
download MSI Afterbuner, and setup a more steeper fan profile curve. i've set mine so when gaming, it sits around 70c (with 65% fan, pretty loud, but not as loud as my speakers, so all good). never exceeds 75c. and Pete J, your temperature might be limiting your overclock, i've found if i turn fan to maximum (85%), i will be able to get 940MHz out of the card, if not, i can only get maximum of 920MHz, before it crashes 3dmark 11.
Yeah, I know. If I go to more than 1.05V the top gpu reaches its thermal limit, and tri SLI means that overclocking on stock voltage doesn't go as far as one or two cards. I would watercool them but I don't have the funds for a few months, not to mention I've just had to buy a new mobo and a copy of windows to go with it.
You could buy a heat exhaust. Fits in rear case pci bay and uses a fan to exhaust air out back of case. Cost only Afew quid and could be positioned right under a card. Con- look pretty fugly, cheap fan inside Worth a afew quid?
i've got those exhaust, useless for all modern cards because they all vent air out the back anyway. it was brilliant for 8800GTX, because it had some vents inside the case, cooking any card under it. with the exhaust sucking those hot air, it cooled the card very well by making sure its surrounding is cool.
